我在使用 Facelets 将项目从我认为的 jsf 1.1 或 1.2 转换为 jsf 2.0 时遇到问题。
我已经阅读了很多有关如何执行此操作的问题，但我仍然遇到问题。我遇到的问题是 jsf 标签没有呈现为 html 标签。
我是 JSF 新手，仍在努力掌握它的窍门。

A very common problem in configuring
MyFaces-web-applications is that the Extensions-Filter is
not configured at all or improperly configured. This
parameter will check for a properly configured
Extensions-Filter if it is needed by the web-app. In most
cases this check will work just fine, there might be cases
where an internal forward will bypass the Extensions-Filter
and the check will not work. If this is the case, you can
disable the check by setting this parameter to false.

Monitors Faces JSP files for modifications and synchronizes a running server with
the changes without restarting the server. If this parameter is set to false or
removed from the deployment descriptor, any changes made to Faces JSP files may
not be seen by the server until it is restarted. This parameter is usually set
to true while the Faces JSP files are being developed and debugged in order to
improve the performance of the development environment.</description>

最佳答案
那么，您想在 Facelets 上使用 JSF 2.0 吗？我猜您还希望能够继续使用旧的 JSP 文件？
混合使用 JSF 1.x 和 JSF 2.x 声明，很难爬过问题中的 web.xml 怪物。关键点是删除 javax.faces.DEFAULT_SUFFIX (您错误地将其设置为 .jsp)并更改 FacesServlet 映射在 *.xhtml 上。
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
此外，您的 ExtensionsFilter 可以更好地映射到 FacesServlet 的单个 servlet 映射上。
<filter-mapping>
<filter-name>extensionsFilter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
这样 Facelets 文件就必须正常工作。当 foo.xhtml 不存在，但 foo.jsp 确实存在时，它将在 *.xhtml URL 模式后面提供服务.
